Pyramid A is a square pyramid with a base side length of 7 inches and a height of 6 inches. Pyramid B has a volume of 3,136 in?.
anygoal [31]

Answer:

WE HAVE FIND HOW MUCH MAY TIME BIGGER IS THE VOLUME OF PYRAMID B THAN PYRAMID A.

The answer is 32 times

Step-by-step explanation:

Volume of Pyramid B = 3136 in³

Volume of Pyramid A = ?

We have to find volume of Pyramid A. As Pyramid is a square pyramid, its volume is given as:

V=\frac{(b^2)(h)}{3}

where b = base = 7  and h = height = 6. Substitute the values:

V=\frac{7^2\cdot6}{3}\\V=98\\

Volume of Pyramid A = 98 in³

To find how many time B is bigger than A, divide volume of B by A:

\frac{3136}{98}=32

So, volume of Pyramid B is 32 times bigger than volume of Pyramid A

Angles ∝ and β are the two acute angles in a right triangle. Use the relationship between sine and cosine to find the value of β
arlik [135]
Ok so cos(x) = sin(90-x) so using that you can get sin(7x-15) = sin(90-(3x+5)) so 7x-15 = -3x+85. 10x = 100 and x = 10. Use that to find the 2 angles are 55 and 35
